Thanks everyone!!
@knotscott Interesting. I think you’re correct about the bass. The midbass was taking care of all but the lowest frequencies, and then crossed over to the sub. This explains how I missed the inactive woofers.
I texted with Dick Diamond of GTT Audio today. He is the former director of sales at YG. He also suggested that I consider bi-amping in the future. In the meantime, I’m excited to get some jumpers connected and hear what the Haileys will produce on their own.
